Welcome, new students, to Maple Knoll High School Library! Here is an introduction of our school library. The 1． on the left of the map helps you best understand it.
The computer lab is just on the 2． of the main entrance. You can enter computers by putting into the 3． of your student ID card. There are 4． copy machines in the library. The circulation desk on the left of the main entrance is a place to borrow and return books from general stacks. The reading area is in the middle of the library. A water fountain is between the 5． and the cellphone area. They’re all on the right.
If you want to ask for more help, you can go to the librarian’s office.

y = sin x， x∈R， y∈[–1，1]，周期为2π，函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x， x∈[–1，1]， y∈[–π/2，π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
